My mother sent me a happy birthday message this morning. What should I call to say?

Just say a few words of thanks, or say thank you for your life with emotion! After all, today, your mother is in endless danger, risking her life to get pregnant for ten months and give birth to you. In any case, it is appropriate to say thank you solemnly. If you are free, you'd better stay with your mother and listen to her nagging ... If you are not a mother, how can you solve her pain? Alas! Birthday is the most painful day for mother, but how many people can understand it?
